Growth of rabbits under different environmental temperatures using high fat diets.

 C. Cervera, E. Blas, J. Fernández-Carmona


686 rabbits, weaned at 35 days of age, were fed ad libitum up to 84 days of age on three diets (composition per kg dry matter: 11.0 MJ DE - 26 g EE; 12.2 MJ DE - 117 g EE mainly from commercial tallow; 12.4 MJ DE, 99 g EE from vegetable origin) and five environments defined by the mean minimum temperatures during fattening of 10-14°C, 14-22°C, 22-26°C, 30°C constant and 33°C constant. Dally gains recorded for those temperatures were 38, 38, 33, 28, 23 g (P<0.001) and feed intake 83, 77, 70, 62, 53 g DM/kg0.75 (P<0.001). Daily gain recorded for the three diets was 31, 32, 33 g (P<0.001) and feed intake 73, 69, 66 g DM/kg0.75 (P<0.001). lnteraction between diet and temperature was significant (P<0.001) for food intake which was similar at high temperatures while for the rest inversely relatad to the DE content of the dieta.
